“Leviathan Sellers was built specifically for the post-2025 landscape. Every process — daily auditing, manufacturing cost documentation, manual individual filing, active denial appeals — was designed from scratch around what Amazon now requires.”

I founded Leviathan Sellers in 2019after working closely with Amazon FBA sellers and seeing first-hand how much money was being silently lost to unclaimed reimbursements, fee overcharges, and IPI issues. When Amazon changed its reimbursement policy in 2025 — cutting the claim window from 18 months to 60 days and switching to manufacturing cost — most existing tools and services simply weren't built to handle it correctly.

Since 2019 I have worked hands-on inside Amazon Seller Central — auditing transactions, preparing manufacturing-cost documentation, filing reimbursement claims, appealing denials, and managing account health for sellers on Amazon US, UK, India, Canada and the EU. Every claim is handled personally, with full documentation, and every recommendation is grounded in real transaction data rather than generic advice.

Our philosophy

We Exist to Recover the Money Amazon Owes You.

Amazon's fulfillment system generates discrepancies at scale. At the volume Amazon operates, a fraction of a percent in errors means real money — your money — sitting in Amazon's account instead of yours.

Our mission: identify every discrepancy, file every valid claim before it expires, document every case correctly under the current manufacturing-cost policy, and appeal every denial. No shortcuts. No automation that risks your account.

We are an authorised Amazon Selling Partner. Every action we take in your account is fully compliant with Amazon's current terms. Your account health is never at risk from our work.
